DESCRIPTION

Procedure to treat a laundry

The present invention relates to a cleaning product for laundry.

Laundry cleaning products are very well known. Normally, a composition in the form of a liquid or powder is added to a washing machine for washing, either directly to the drum or by means of a dispenser, and the washing is carried out using an appropriate selection of several previously programmed cycles. Accurate dosing can be a problem, particularly when consumers do not read or do not follow the dosing instructions. Recently, products in the form of washing compositions packaged in a water-soluble polymer film have been made available. However, alternative procedures for presenting products in unit doses are desired. In addition, there may be a preconceived idea in the minds of some consumers that the polymer may not dissolve completely or that the polymer may dissolve before the product is added to the wash. Additionally, the product is perceived as fragile, and lacks versatility in use.

Compositions for pretreating a laundry item are also known, for example to remove a stain or to aid in the removal of stains. Such compositions are in the form, for example, of a liquid composition that can be applied directly to the garment for washing, for example, by spraying. However, normally such compositions need to be rinsed with water after use, for example, by hand or in a washing machine for washing clothes.

GB-A-340 077 describes a method of treating fabric stains comprising the use of an absorbent separated from the fabric by a thin fabric.

The inventors have now found certain active agents in the form of a solid (preferably in the form of a powder) that can be used to remove dirt from laundry clothes that do not need to be rinsed with water after use, but which the user can remove. easily brushing

Accordingly, a first aspect of the present invention provides a washing product having a closure wall and containing a composition in the form of a powder, said composition comprising an insoluble active agent that can bind to dirt or free dyes, being the water permeable wall and components dissolved in it, in which, after contacting the product with the water in a washing machine for washing, the insoluble active agent remains inside the closing wall, characterized in that the wall of closure comprises a stain and dye trap as a charge in an amount of 0.1 to 60% by weight.

Preferably, a laundry item is brought into contact with the product when it has just become dirty. Therefore, the cleaning composition can be applied to the garment for washing within 30 minutes after the dirt is produced, preferably within 10 minutes, for example within 1 minute. If desired, the laundry item can be wetted or moistened to help the cleaning composition come in contact with the stain.

Then, the composition can be left on the dirty area for a sufficient time to allow the insoluble active agent to bind or "trap" the dirt / stain particles (by using the term dirt the inventors also include stains). This may last less than 1 hour, for example less than 30 minutes, preferably less than 10 minutes.

The cleaning composition may contain at least one additional active agent, such as a surfactant and / or bleach. The surfactant or bleach may dissolve at least in part after contact with the dirt. The surfactant or bleach can be oil soluble and / or water soluble. Suitable surfactants and bleaching agents are described in detail below.

Although the cleaning composition may contain a surfactant, the amount of surfactant in the cleaning composition is preferably less than 30 percent by weight, more preferably less than 20 percent by weight, even more preferably less than 10 percent by weight, for example, less than 5 percent by weight. In one embodiment, the composition comprises less than 3 percent by weight of surfactant. In another embodiment, the composition is substantially free of surfactant.

Any suitable dirt trap can be used. Unlike detergents or surfactants, which simply help in removing dirt from surfaces, the dirt trap actively binds to dirt allowing it to be removed from the surface of laundry. Once attached, dirt is less likely to be able to be repositioned on the surface of laundry. Preferred dirt catchers have a high affinity for both oily and water soluble dirt. Preferably, the dirt trap is a mixture of two or more dirt trappers, each dirt trap can have a different affinity for different dirt. Preferred dirt catchers for oily dirt have a non-polar structure with high absorption capacity. Preferred water-based dirt catchers are generally charged and have a high surface area in order to attract dirt by loading.

Electrostatic and pick it up.

Suitable dirt trappers include polymers, such as acrylic polymers, polyesters and polyvinyl pyrrolidone (PVP). The polymers may be crosslinked, examples of which include crosslinked acrylic polymers and crosslinked PVP. The superabsorbent polymers are mainly acrylic polymers and are useful for the scope of this patent. Other important polymers are ethylidene norbornene polymers, ethylidene norbornene / ethylene copolymers, ethylidene norbornene / propylene / ethylidene terpolymers. Inorganic materials can also be used. Examples include silica, silicates (for example, magnesium silicate), zeolites, talc, bentonites and active carbon. The latter can be used to absorb and / or degrade colored spots of stain and / or absorb odors. Alginates, carrageenans and chitosan can also be used. Preferred water insoluble agents are selected from at least one of acrylic polymer, polyester, polyvinylpyrrolidone (PVP), silica, silicate, zeolite, talc, bentonites, active carbon, alginates, carrageenans, ethylideneorborne / propylene / ethylidene terpolymers and chitosan in the preparation of a cleaning composition as an active agent to bind to dirt. Preferably, the cleaning composition is a laundry cleaning composition or stain removal composition.

Preferably, the water insoluble dirt trapping compound would comprise a solid crosslinked poly (N-oxide) or chitosan product or ethylidene-norbornene / propylene / ethylidene terpolymers or mixtures thereof, as discussed in detail below. Products prepared according to the present invention that are suitable for individual use can be provided in a variety of ways, but at least they will contain a compartment for storing a water insoluble dirt trapping compound and will have a plurality of openings, as previously described.

The laundry products of the present invention can be used with a variety of water insoluble dirt trapping compounds. These water insoluble dirt trapping compounds can be provided as a solid, gel, and the like.

These dirt trapping compounds can release the benefit of the dirt trap through a variety of techniques that include, but are not limited to, trapping the dirt in such a way that it is not available for redeposition on a fabric, precipitating dirt or adsorbing, absorb or otherwise associate any external dirt in the wash water.

As used herein, the term "substantially insoluble in water" is intended to mean that the dirt trapping compound has a solubility in deionized water at 20 ° C of less than about 1 g / liter. A substantially water insoluble dirt trapping compound can comprise a water soluble dirt trapping agent that is attached to a water insoluble vehicle, or it can comprise a dirt trapping agent that itself is water insoluble. Water insoluble carriers for water soluble polymeric agents include inorganic materials such as zeolites, clays such as kaolinites, smectites, types of hectorites, silicas (or other detergent components). Additionally, water-insoluble organic materials such as fatty alcohols, fatty acid esters, or polysaccharides that can form water-insoluble gels after hydration (e.g., gellan gum, carrageenan gum, agarose, etc.) can be used as carriers. this respect. For soil-trapping agents that are water soluble in themselves, water insolubility can be achieved by crosslinking, either starting from known water-soluble soil-trapping polymeric agents, or starting from monomers of these polymers. Other compounds that are suitable as water insoluble dirt trapping agents are any compound that has ion exchange properties, preferably anion exchangers. For example, non-limiting examples of such products are Dowex (R) exchange resins from Dow Chemical Co.

or equivalent of other suppliers; Sephadex (R), Sepharose (R) or Sephacel (R) exchange resins, all from Pharmacia Biotech; any other polysaccharide having ion exchange properties such as modified cellulose fibers, starches; other derivatives of the wood industry such as wood pulp or lignin.

Water soluble dirt trapping polymeric agents that are suitable to bind to insoluble vehicles, or to become insoluble by crosslinking, are the polymers known in the art to inhibit the transfer of colored fabric dyes onto fabrics washed therewith. These polymers have the ability to complex or adsorb fugitive dyes washed from colored fabrics before the dyes have the opportunity to bind to other items in the wash. Especially suitable dirt trapping polymeric agents are poly (N-oxide amine) polymers, polymers and copolymers of N-vinylpyrrolidone and N-vinylimidazole, vinylxazolidones, vinylpyridine, vinylpyridine N-oxide, other vinylpyridine derivatives or mixtures of the same.

it was determined by light scattering as described in Barth H. G. and Mays J. W. Chemical Analysis vol 113, "Modern Methods of Polymer Characterization." The most preferred N-vinylimidazole and N-vinylpyrrolidone copolymers have an average molecular weight range of about 5,000 to about 50,000; more preferably from about 8,000 to about 30,000; most preferably from about 10,000 to about 20,000. The copolymers of N-vinylimidazole and Nvinylpyrrolidone characterized by having said average molecular weight range provide excellent dirt trapping properties. The copolymer of N-vinylimidazole and N-vinylpyrrolidone has a molar ratio of N-vinylimidazole to N-vinylpyrrolidone of about 1 to about 0.2, more preferably about 0.8 to about 0.3, and most preferably about 0.6 to about 0.4

c) Polyvinylpyrrolidone

Polyvinylpyrrolidone ("PVP") having an average molecular weight of approximately approximately can also be used.

2,500 to about 400,000; preferably of average molecular weight from about 5,000 to about 200,000; more preferably from about 5,000 to about 50,000; and most preferably from about 5,000 to about 15,000. Suitable polyvinylpyrrolidones are commercially available from ISP Corporation, New York, N.Y. and Montreal, Canada, under the product names PVP K-15 (viscosimetric molecular weight of 10,000), PVP K-30 (average molecular weight of 40,000), PVP K-60 (average molecular weight of 160,000) and PVP K-90 (average molecular weight of 360,000). Other suitable polyvinylpyrrolidones that are commercially available from BASF include Sokalan HP 165 and Sokalan HP 12; polyvinylpyrrolidones known to experts in the field of detergents (see, for example, EP-A-262,897 and EP-A-256,696).

d) Polyvinyloxazolidone

Polyvinyloxazolidone can also be used as a polymeric dirt trapping agent. Said polyvinyloxazolidones have an average molecular weight of about 2,500 to about 400,000; preferably from about 5,000 to about 200,000; more preferably from about 5,000 to about 50,000; and most preferably from about 5,000 to about 15,000.

e) Polyvinylimidazole

Polyvinylimidazole can also be used as a polymeric dirt trapping agent. Such polyvinylimidazoles have an average molecular weight of about 2,500 to about 400,000; preferably from about 5,000 to about 200,000; more preferably from about 5,000 to about 50,000; and most preferably from about 5,000 to about 15,000.

f) Cationic polymers

Such polymers are those that have a cationic group in their polymer backbone, as shown by the formula:

[P-Catx] n-Zt-Caty

wherein P represents polymerizable units, Z represents an alkyl, aryl, carbonyl, ester, ether, amide or amine group, Cat represents cationic groups that preferably include quaternized N groups or other cationic units, x = 0 or 1, y = 0 or 1, t = 0 or 1. The preferred cationic polymers are quaternized polyvinylpyridines.

Water insolubility can also be achieved, in the case of non-crosslinked polymers, by selecting a very high molecular weight range, or by copolymerizing, or by varying the degree of oxidation, if appropriate, depending on the polymer. Polymers that are water soluble, such as those described in US Pat. No. 5,912,221, can be made insoluble if the molecular weight increases above 400,000.

g) Crosslinked polymers

Crosslinked polymers are polymers whose skeletons are interconnected to a certain degree; these links can be chemical or physical in nature, possibly with active groups in the skeleton or branches; crosslinked polymers have been described in Journal of Polymer Science, volume 22, pages 1035-1039. In one embodiment, the crosslinked polymers are prepared in such a way that they form a rigid three-dimensional structure that can trap dyes in the pores formed by the three-dimensional structure. In another embodiment, the crosslinked polymers trap the dyes by swelling. Such crosslinked polymers are described in US Pat. No. 5,912,221.

Thus, a crosslinked polymer has one or more individual molecular chains linked by side chains to adjacent chains. Crosslinks can be formed: (a) between existing linear or branched polymers,

(b) during polymerization of multifunctional monomers or (c) during polymerization of dimer monomers with traces of multifunctional monomers. Crosslinking can also be achieved by various means.

known in the art. For example, cross-links can be formed using radiation, oxidation and curing agents such as divinylbenzene, epichlorohydrin and the like. Preferably, the crosslinked polymers are those obtained by crosslinking a water soluble dirt trapping polymer described above with a divinylbenzene crosslinking agent (DVB) during polymerization of the soil trapping monomer. The degree of crosslinking can be controlled by adjusting the amount of divinylbenzene crosslinking agent (DVB). Preferably, the degree of cross-linking is between about 0.05% by weight of DVB relative to the dirt trap monomer and about 50% DVB relative to the dirt trap monomer and, more preferably between about 0.05% by weight of DVB with respect to the dirt trap monomer and approximately 25% by weight of DVB with respect to the dirt trap monomer. Most preferably, the degree of cross-linking is between about 0.1% by weight of DVB relative to the dirt trap monomer and about 5% by weight of DVB relative to the dirt trap monomer. Cross-linking forms particles of dirt trapping compounds of which at least 90% of the total particle weight (and more preferably at least about 95%) has a d50 particle size of at least about 1 µm, preferably at least about 50 µm, and more preferably at least about 75 µm, all measured in its dry state. The d50 particle size is the particle size or the weighted median of the particle diameter at which 50% by weight of the particles are greater than, and 50% by weight are less than. It can be properly determined by mechanical screening. Most preferably, the crosslinking forms dirt trapping compounds of which at least 90% (and more preferably at least about 95%) has a d50 particle size of between about 1 µm and about 5 mm, still more preferably of between about 50 µm and about 2500 µm, and even more preferably between about 75 µm and about 1500 µm, all measured in their dry state. Preferably, the crosslinked polymer is a poly (amine oxide) or a quaternized polyamine. The person skilled in the art can conveniently obtain such compounds by oxidizing or quaternizing crosslinked polyvinylpyridines from Reilly Industries Inc. marketed under the name Reillex (TM) 402 or Reillex (TM) 425 by methods known in the art. For example, but not exclusively, the procedure described in US Pat. No. 5,458,809 can be used to prepare a poly (amine oxide) of interest from the commercially available compounds provided above. An example of quaternized polyamine can also be obtained from Reilly Industries under the trade name Reillex (TM) HPQ.

Superabsorbent polymers such as crosslinked acrylic polymers are useful within the scope of this patent. Examples are qualities of Alcosorb de Ciba, Acusol de Rohm & Haas and Cabloc de Degussa.

Other important polymers are ethylidene norbornene polymers, ethylidene norbornene / ethylene copolymers, ethylidene norbornene / propylene / ethylidene terpolymers.

The dirt trap may be present in the cleaning composition in an amount of 0.01 to 100% by weight of the composition, preferably 1 to 90% by weight, more preferably 5 to 50% by weight.

The cleaning composition may optionally contain a charge. Suitable loads are described in detail below. The cleaning composition may also contain additives such as adjuvants, chelating agents, solvents, enzymes, fragrances and anti-caking agents as described in greater detail below.

The cleaning composition is in the form of a powder. By "powder" the inventors mean any solid fluid composition. Therefore, the powder may be, for example, in the form of granules or agglomerated particles. However, it may be in the form of a loose agglomeration of particles. The particle size d50 of the particles may range from 0.001 µm to 10 mm, preferably from 0.01 µm to 2 mm, and more preferably from 0.1 µm to 2 mm, for example from 1 µm to 1 mm.

The cleaning composition is enclosed in a closing wall or container that is permeable to water and components dissolved therein. Such an enclosed product can be used in the washing cycle of a laundry washing machine.

The washing product of the present invention combines the advantages of a unit dose product with an active agent that can bind dirt or "dirt trap" product.

The composition advantageously further comprises cleaning agents selected from the group consisting of surfactants, bleach, activators, enzymes or a mixture thereof. These active agents are generally soluble in water, so they dissolve during washing. Therefore, additional active agents are released for a period of time when exposed to water in the washing machine for washing.

An advantage of the present invention is that the cleaning product is more versatile since the closing wall can have an additional function. For example, the product can be contacted or applied to the laundry to be washed before being added to the laundry washing machine. In this way a pretreatment can be carried out depending on the nature of the product.

The cleaning product has a closure wall that is permeable to water and components dissolved therein. The closing wall can also be permeable to oils and other dirt or stain components suspended or dispersed in water.

However, the wall is impervious to dust contained within the product.

The closing wall may have a part that is insoluble in water and permeable to water, and another part that is insoluble in water and impervious to water. In use, a user can hold the product by the waterproof wall section and, for example, press the permeable wall section directly with the stain. This avoids contact between the user's hands and the contents of the closing wall.

By water permeable, we want to indicate that the inventors have a water permeability of at least 1000 l / m2 / s at 100 Pa according to DIN EN ISO 9237. In addition, the wall must not be so permeable that it cannot contain the powder composition . Thus, for example, the wall may have a mesh size of less than 250 micrometers, preferably less than 150 micrometers, more preferably less than 50 micrometers.

The product must not be able to exit the drum, entering the internal network of washing machine pipes and the filter. Therefore, if it is intended to be added directly to the drum, it is generally large, preferably having a minimum length and width of at least 120 mm.

The product is preferably flat, that is, its thickness is at least 5 times less, preferably at least 10 times less, ideally at least 30 times less than each of its other two dimensions, the width and length (which are the same as the two when the product is square or circular).

The product can be placed with the laundry to be washed in an automatic laundry washing machine. The closed product preferably resists a laundry wash cycle (wash / rinse / spin cycle of 2 h, 95 ° C, centrifuged at 1600 rpm) without opening. The product can be discarded after use.

The product can also be used in a stain treatment stage before placing it in an automatic laundry washing machine. For example, the product can be wetted with water and used directly on the stain by a rubbing action. When the composition begins to dissolve, it can be released through the closure wall or container to the area of treated garments.

Alternatively, the washing product can be placed in a bucket with water and dirty laundry. After soaking laundry clothes for a predetermined period of time, laundry clothes can be removed. In one embodiment, the laundry is soaked for a period of time ranging from 1 minute to overnight, preferably from 10 minutes to 6 hours.

The product can form a flat container or envelope. The envelope can be at least 2 cm wide. Preferably, the envelope is at least 10 cm wide. The envelope is preferably large enough to be conveniently held by hand and applied directly to the laundry for dirty washing.

The envelope can be formed from a two-veiled sandwich. A sheet or film permeable to water is present in one of the veils, at least, and forms at least one wall of the container. The outer water permeable wall may comprise, for example, a woven, knitted or preferably nonwoven material, of textile, polymer or paper. Suitable polymers include cellular polymer materials. The material may be in the form of a single layer or laminated layers. Preferably, the wall comprises a sheet with a layer of fabric of one, two or three layers, so that any undissolved or insoluble agent inside the container is too large to pass through the perforation (s) or have to follow an impossibly sinuous path if it were to leave the vessel by the wall. Preferably, the sheet is a woven or nonwoven material.

The product can conveniently comprise two veils sealed together around its periphery, with the contents held inside. The sealing can be by means of adhesive or dielectric welding or, preferably, heat sealing, or most preferably, ultrasonic sealing. If the sealing is by heat sealing, the sheets may comprise a thermoplastic material to facilitate this. The material that forms the adhesive strips may be a so-called hot melt comprising various materials, such as APP, SBS, SEBS, SIS, EVA and the like, or a cold glue, such as a dispersion of various materials, for example, SBS, rubber natural and the like, or even a solvent based adhesive system or one of two components. In addition, the material may be able to crosslink to form specific permanent chemical bonds with the various layers. Polyethylene glycols with different molecular weights that have average molecular weights ranging from 1000 to 20,000 can also be used, the most preferred being from 2000 to 8000. The amount of adhesive used is a function of the type of adhesive selected. However, it is generally 0.2 to 20 g / m2.

Conventional materials used in the manufacture of tea bags or in the preparation of hygienic products or diapers may be suitable, and the techniques used in the preparation of tea bags or hygienic products may be applied. Such techniques are described in WO 98/36128, US-A-6,093,474, EP-A

708.628 and EP-A-380.127. US 5,053,270 also describes a process for forming a product.

flexible.

Conveniently, the two veils are nonwoven. The procedures for manufacturing nonwoven fabrics can be grouped into four general categories that lead to four main types of nonwoven products, combinations related to paper-related textiles, related to the processing of extrusion polymers and hybrids.

Textiles Textile technologies include fraying, carding and aerodynamic fiber formation in selectively oriented veils. The fabrics produced by these systems are hereinafter referred to as nonwovens arranged dry and carry terms such as frayed, carded and airborne fabrics. Textile-based nonwoven fabrics, or fiber network structures, are manufactured with machinery designed to handle textile fibers in the dry state. Also included in this category are structures formed with filament bundles or bast, and fabrics composed of cut fibers and sewing threads.

In general, procedures based on textile technology provide maximum product versatility since most textile fibers and bonding systems can be used.

Paper. Paper-based technologies include dry-disposed pulp and (wet-modified paper) systems designed to accommodate short synthetic fibers, in addition to wood pulp fibers. Fabrics produced by these systems are hereinafter referred to as pulp disposed in dry and nonwovens disposed in wet. Paper-based nonwoven fabrics are manufactured with machinery designed to handle short fibers suspended in fluid.

Extrusions Extrusions include spun, molten and blown and porous nonwoven film systems. The fabrics produced by these systems are hereinafter individually referred to as nonwovens of spun, melted and blown and textured or with openings, or generically nonwovens arranged in polymers. Nonwovens based on extrusion are manufactured with machinery associated with the extrusion of polymers. In systems arranged in polymers, fiber structures are formed and manipulated simultaneously.

Hybrids Hybrids include systems that combine fabric / sheet, combination systems and composite systems. Combination systems employ lamination technology or at least one basic non-woven veil formation or consolidation technology to join two or more fabric substrates. Combination systems use at least one fabric substrate. Composite systems integrate two or more basic nonwoven vein formation technologies to produce veil structures. Hybrid procedures combine the advantages of technologies for specific applications.

Suitable materials for forming the closure wall are paper or a polyolefin, such as polyethylene or polypropylene, or another polymer such as a polyester or polyamide. Suitably, the closure wall comprises a water insoluble veil permeable to water, preferably one or a mixture of the above materials. The closure wall is preferably a veil of woven or nonwoven. The materials constituting the closing wall are preferably in the form of fibers.

The surface of the closing wall can be subjected to corona or plasma treatment or a permanent chemical treatment, for example with cationic polymers. All these treatments can lead to an increase in the affinity of organic molecules for the substrate through ionic or polar interaction. By doing this, the free stain molecules in the wash water are captured by the wall of the product that acts as a filter, reducing the redeposition of stains on the fabrics.

The closing wall can also be formed of a cellular plastic material. Cellular plastics suitable for forming the closure wall have densities of 1 to 500 kgm-3, preferably 20 to 80 kgm-3 and with an average pore diameter of at least 0.1 mm, preferably at least 0.4 mm Ideally, cellular plastics have a porosity greater than 50%, preferably greater than 60%, more preferably greater than 70%, most preferably greater than 80%.

Porosity is determined using a dry automatic densimeter to measure the apparent volume and actual volume of cellular plastic material. Then, the porosity is calculated according to the following equation:

Porosity% = [(apparent volume - actual volume) / apparent volume] x 100

The "average pore diameter" is a value measured according to the ASTM standard (designation: D4404-84) and is specifically a value determined by the measurement of the pore diameter according to a mercury penetration procedure using a porous mercury manufactured by Porous Material, Inc.

Suitable cellular plastic materials are those readily available from, for example, Euro foam, Miarka and Menshen and are prepared from any suitable water insoluble plastic such as cellulose, polyurethane, polyester, polyether or mixtures thereof.

rough outer surface can be provided by the wall being in the form of woven or nonwoven fibers. The roughness of the surface depends on, for example, the diameter of the fibers. The rough outer surface can also be provided by ensuring that an otherwise uniform outer wall has a surface texture. This could be provided, for example, by including particulate material on the wall or by forming the wall in an appropriate manner. A rough outer surface can provide several advantages. For example, it ensures that the product is less likely to slip from the consumer's hand, particularly when the product is wet and therefore slippery. It also helps in a secondary function of the product, which is to provide a pretreatment of laundry to wash before washing. The product can simply be put in contact with or applied to the laundry to be washed, especially a stained part thereof, to treat the laundry to be washed before washing, for example to remove a stain or assist in the removal of stains. Some of the cleaning compositions inside the product can be filtered outside to aid in this pretreatment. It is also possible for an additional agent to join the outside of the product.

The closing wall of the product can be a cellulosic material, for example a cellulosic textile or paper material.

The product of the present invention is preferably such that, after contact with water in a utensil washing machine, less than 80% by weight of the cleaning composition remains, preferably less than 50% by weight and most preferably less than 30% by weight. This is with reference to the product placed in the drum of a usual washing machine for washing, such as a Bosch WFR 3240 washing machine, in a usual washing cycle, in particular a cotton cycle at 40-60 ° C, and at any hardness of the water, but preferably at a water hardness of 18 to 24 ° dH (German grades). Preferably, at least 5, 10, 15, 20 or 25% by weight of the cleaning composition remains in the product after it has thus been brought into contact with water in a utensil washing machine. The residue in the product is preferably mainly composed of the dirt trap. In another embodiment of the present invention, the product can be fully opened during the wash cycle in the wash drum by releasing all its contents and joining loose dye and dirt on the product wall. Preferably, a washing machine for washing Bosch WFR 3240 is used in a cotton cycle at 60 ° C and at a water hardness of 18 ° dH. For the avoidance of doubt, even when this test uses a particular laundry washing machine, the laundry treatment product of the present invention can be used in any laundry washing machine in any cycle. If the product satisfies the previous test, it can be used in any laundry machine to wash in any cycle.

Sources of active oxygen increase the ability of the compositions to remove oxidizable stains, to destroy malodorous molecules and to kill germs.

The concentration of available oxygen can be determined by methods known in the art such as the home appliance, the permanganometric procedure and the cerimetric procedure. Such procedures and the criteria for choosing the appropriate procedure are described, for example, in "Hydrogen Peroxides", WC Schumo, CN Satterfield and RL Wendosrth, Reinhold Publishing Corporation, New York, 1955 and "Organic Peroxides", Daniel Swern, Editor Wiley Int.

5 Stain removal test

To test the effect of Examples 1 to 53 on oil-based stains, 0.1 grams of walnut oil was applied directly onto blue WFK cotton samples. To test the effect of examples 1 to 53 on water-based stains, 0.15 grams of tea and grape juice were applied on samples of Tic 400 WFK cotton. The spots were left for 10 minutes before cleaning.

10 In the cleaning procedure, 4 grams of the dirt trap powders of Examples 1 to 53 were used to treat the stain. Dirty areas were rubbed with a small sponge in order to improve contact between the stain and the dust. Then, the powder was allowed to act for 10 minutes and then removed by brushing with 5 scrubbing actions in the vertical direction and 5 in the horizontal direction.

Tea stains and grape juice were evaluated by a spectrophotometer measuring the values of

E05252345

06-09-2015

reflectance The X Y Z scale was used with a spectrophotometer with the UV filter at 460 nm. Y = 90 means one

complete stain removal (white cotton has a value of 90). The nut oil stain on blue samples was evaluated by a panel test with a rating between 1 and 5. A rating of 1 was given in cases where the stain was completely removed.

5 An assessment of 5 was given in cases where the stain was unchanged.

The ease with which the dirt trap dust could be removed from the samples was also assessed by a panel test using a rating of 0 to 4 in which: 0 = no residue 1 = low residue

10 2 = medium residue 3 = medium / high residue 4 = a lot of residue (sticky) The results are shown in the tables given below.
